Cellphone antennas come in various sizes, but their objective remains the same; to augment the signal and boost the capabilities of the phone. Owing to the varied cellphone models around, the antennas now have diverse specifications as well. The following examples are from Wilson Electronics.
Cellphone Antenna Dimensions: Wilson Magnet Mount
The Wilson Magnet Mount antenna is 12 inches long and uses an RG-174U coax cable. The connector is FME Female and the coils are 1 open and 1 closed. To use the antenna, a plane is required (like metal plate on automobiles).
The wavelengths are 9 806-894 MHz and 2.0 1850-1990 MHz. The impedance is 50 Ohms (both bands). The antenna gain specs are: 6.12dBi in 1850 – 1990 MHz and 3dbd / 5.12dBi in 806 – 894 MHz. The antenna was designed to keep loss to a minimum on the 1900 MHz and the 800 MHz bands.
Cellphone Antenna Dimensions: Wilson Electronics Cellular Glass Mount
The Wilson Electronics Cellular antenna whip is 15" high. It comes with a 14 ft of RG-58 coax cable. The antenna gain is 5.9 dBi in 1850-1990MHz and 4.5 dBi in 806-894MHz. The system gain is 10-15 dB.
The wavelength specs are 1.1 806-894 MHz and 2.3 1850-1990 MHz. The unit has a ground plane built in. The connector is FME Female. The glass mount comes with adhesive pads.
To get the best signal possible, the device should not be set on defrogger wires. This will generate a poor signal. In addition, the wires might get broken when you take off the antenna.
Cellphone Antenna Dimensions: Wilson Marine Antenna
The Wilson Marine Antenna is 21 inches / 53.3 cm high (this is with the coupler). The coax cable used is RG58 (7 inches / 17.18 cm). The whip is made up of stainless steel, while the casing is made of fiberglass. The frequency range is 806-894 MHz / 1850-1990 MHz. The gain is 5.12 dBi 806-894MHz / 6.12 dBi 1850-1990 MHz.
The polarization is vertical and the wavelength at 0.9 806-894 MH / 1.95 1850-1990 MHz. Other features are omni directional capabilities, chrome plated ground plane, and it can be set on 1 inch x 14 threaded mounts.
This unit is designed for use in small boats, yachts and other vessels. However it can also just as easily be used to amplify signals in the home or office.
Cellphone Antenna Dimensions: the Wilson Trucker NMO Hole Mount
The Wilson Trucker NMO Hole Mount is 13.25 inches / 33.7 cm high. The antenna is 32”. The whip is made of stainless steel and it uses an FME Female connector. The wavelength specs are: 1.0 806-894 MHz / 2.1 1850-1990 MHz. The polarization is vertical.
The antenna gain is 4.9 dBi 806-894 MHz / 5.9 dBi 1850-1990 MHz and the impedance is 50 ohms. The frequency range is 806-894 MHz / 1850-1990 MHz. The coax cable is RG-58 / 12′. The device must be placed on a metal surface.
The cellphone antenna dimensions play a huge part in determining how well the device works. Of course, the mechanical and electrical properties are also very important.
